Metamaterial and its preparation method, metamaterial satellite antenna and satellite receiving system

Abstract

The invention provides a metamaterial and a preparation method of the metamaterial. The metamaterial includes a first glass reinforced plastic (GRP) support, a second GRP support, and a metamaterial working layer internally arranged between the first GRP support and the second GRP support, wherein the metamaterial working layer includes at least one metamaterial working slice layer; the metamaterial working slice layer includes a substrate and a metal micro structure attached to the surface of the substrate; the substrate is a polyimide film. The invention further relates to a metamaterial satellite antenna prepared from the metamaterial and a satellite receiving system. The curved surface metamaterial is prepared in a manner that the polyimide film serves as the substrate and GRP serves as the supports, so as to overcome the defect of the traditional method that only a planar metamaterial can be prepared; the curved surface metamaterial can be connected in an assembled manner to prepare a large hollow cylindrical metamaterial satellite antenna; through the GRP supports, the metamaterial satellite antenna can maintain remarkable performance and a longer service life in a hostile outdoor environment.

Description

【Technical field】 [0001] The invention relates to the field of supermaterials, in particular to a supermaterial and a preparation method, a supermaterial satellite antenna and a satellite receiving system. 【Background technique】 [0002] Metamaterials are materials that can modulate electromagnetic waves developed in the past ten years. Metamaterials are generally composed of a certain number of metal microstructures attached to a substrate with certain mechanics and electromagnetism. These microstructures with specific patterns and materials can modulate electromagnetic waves of specific frequency bands passing through them. [0003] Electronic products are developing in the direction of thinning, high performance and multifunctionality. For this reason, substrate materials should not only have low dielectric constant and dielectric loss, but also have excellent thermal, electrical and mechanical properties. [0004] At present, the realization of metamaterial structure is...

AI Technical Summary

Problems solved by technology

[0004] At present, the realization of metamaterial structure is to make metal wires on rigid PCB or other resin boards. Therefore, the processed metamaterial is a rigid flat structure, which cannot realize the production of large and curved antennas.
